Answer : C
Explanation:
a star produces energy by combining two atoms into one creates a powerful burst of energy
Answer:
That's an interesting question to ask as minimum molecular mass is the important thing
As given inn the data the manganese present is equal to 0.818. That's mean hundred gram of protein will contain = 0.412 g of manganese
and we know that molar mass of manganese is equal to 54.938 u
so we will calculate that in 100 g we will have the 0.818/54.938 moles of manganese which will be equal to 0.0149 g moles of manganese.
and in totall 100 gram of protein
1mole= 100/ 0.0149 = 6711 g/mol of protein minimum molecular mass
Explanation:
Scientists don’t know everything. If they did, there would be no need for any more science. Also because the questions are too difficult and we don't have the technology to prove the answers. so they're uncertain.
Answer:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

<u>Answer:</u> The percentage abundance of and isotopes are 77.5% and 22.5% respectively.
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
Let the fractional abundance of isotope be 'x'. So, fractional abundance of isotope will be '1 - x'
- <u>For isotope:</u>
Mass of isotope = 35 amu
Fractional abundance of isotope = x
- <u>For isotope:</u>
Mass of isotope = 37 amu
Fractional abundance of isotope = 1 - x
Average atomic mass of chlorine = 35.45 amu
Putting values in equation 1, we get:
Percentage abundance of isotope =
Percentage abundance of isotope =
Hence, the percentage abundance of and isotopes are 77.5% and 22.5% respectively.
